Ibyiza nibibi byimyanya itandukanye Kinini nini ya diameter kuki bigoye guhinduka? Nigute wabikemura?
Gutondekanya ukoresheje n'imikorere
Umuyoboro wa troncation ukoreshwa cyane cyane kugabanya cyangwa guhuza urujya n'uruza. Harimo irembo, irembo ryisi, diaphragm valve, imipira yumupira, icyuma gipima, disiki ya disiki, plunger valve, imipira yumupira, imashini yubwoko bwibikoresho, nibindi.
Kugenzura valve ikoreshwa cyane cyane muguhindura imigendekere yikigereranyo, igitutu, nibindi birimo kugenzura valve, trottle valve, kugabanya valve nibindi.
Kugenzura indangagaciro zikoreshwa mukurinda itangazamakuru gusubira inyuma. Reba ububiko bwubwubatsi butandukanye burimo.
Imyanya itandukanye ikoreshwa mugutandukanya, gukwirakwiza cyangwa kuvanga itangazamakuru. Harimo imiterere itandukanye yo gukwirakwiza valve n'umutego, nibindi.
Umutekano wumutekano wo gukandamiza hagati mugihe kurinda umutekano. Ubwoko bwose bwumutekano wumutekano urimo.
Bishyizwe mubikorwa byingenzi
(a) ukurikije ibyiciro by'ingutu
Umuyoboro wa Vacuum ukora munsi yumuvuduko ukabije wikirere.
Umuvuduko muke wa valve Valve hamwe numuvuduko wizina PN munsi ya 1.6MPa.
Umuvuduko ukabije wa valve nominal igitutu PN2.5 ~ 6.4MPa valve.
Umuvuduko mwinshi wa valve nominal igitutu PN10.0 ~ 80.0MPa valve.
Umuvuduko mwinshi wumuvuduko wa nominal umuvuduko PN urenze 100MPa valve.
(2) ukurikije ubushyuhe bwo hagati
Ubushyuhe bwo hejuru bwa valve t ifite agaciro karenze 450C.
Ubushyuhe bwo hagati ya 120C munsi ya T 450C.
Ubushyuhe busanzwe -40C
Ubushyuhe bwa T munsi ya -100C.
(3) ukurikije ibikoresho bya valve umubiri
Ibikoresho bidafite ibyuma: nka ceramic valve, valve ya FRP, plastike.
Umuyoboro wibyuma: nkumuringa wumuringa wumuringa, aluminiyumu ya aluminiyumu, icyuma cyitwa alloy valve, titanium alloy valve, Monel alloy valve
Shira icyuma, icyuma cya karubone, icyuma cyuma, icyuma gike cyuma, icyuma kinini.
Umubiri w'icyuma utondekanye na valve: nk'umurongo uteganijwe kurongora, umurongo wa pulasitike utondekanye, umurongo wa emamel.
Sisitemu rusange
Ubu buryo bwo gutondekanya ntabwo bukurikije ihame, imikorere n'imiterere, nuburyo bukoreshwa cyane mubyiciro mugihugu ndetse no mumahanga. Mubisanzwe, hariho amarembo, amarembo yisi, ububiko bwa trottle, ibikoresho byabigenewe, plunger valves, diaphragm valves, plug valves, imipira yumupira, ibinyugunyugu, kugenzura valve, igitutu kigabanya indangagaciro, indangagaciro z'umutekano, imitego, kugenga indangagaciro, indangagaciro zo hasi, filteri , impanuka zo kumeneka, nibindi
Kuki bigoye guhindura kalibiri nini? Nigute wabikemura?
Isesengura ryimpamvu zitoroshye mugukingura no gufunga diameter nini ya diameter
Impuzandengo y'abakuze itambukiranya imipaka isohoka ni 60-90kg, bitewe na physique itandukanye.
Icyerekezo rusange cyerekezo cyisi ya valve yagenewe kuba hasi kandi muremure. Iyo valve ifunze, umubiri wumuntu usunika intoki mu buryo butambitse kugirango uzunguruke, kuburyo disiki ya valve igenda hepfo hanyuma igafunga. Muri iki gihe, guhuza ibintu bitatu byingufu bigomba kuneshwa, aribyo:
1) imbaraga za jacking imbaraga Fa;
2) Imbaraga zo guterana hagati yo gupakira na valve stem Fb;
3) Uruti ruhuza disiki yibanze hamwe nimbaraga zo guterana Fc
Umuriro wose ni M = (Fa + Fb + Fc) R.
Birashobora kugaragara ko uko kalibiri nini, nini nini ya axial jacking imbaraga. Iyo yegereye leta ifunze, imbaraga za jacking imbaraga zegeranye hafi yumuvuduko nyawo wumuyoboro (kuko P1-P2P1, P2 = 0 iyo ifunze).
Kurugero, DN200 ya Calibre globe valve ikoreshwa kumuyoboro wa 10bar, kandi * ijambo ryayo rifunga axial Fa = 10R2 = 3140kg. Imbaraga zitambitse zisabwa kugirango zifunge zegereye imipaka yimbaraga zitambitse umubiri usanzwe ushobora gusohoka. Kubwibyo, biragoye cyane kumuntu gufunga burundu valve muriyi mikorere.
Birumvikana ko inganda zimwe zisaba gushiraho ubu bwoko bwa valve muburyo butandukanye, bukemura ikibazo cyingorabahizi gufunga, ariko harikibazo cyo gufungura nyuma yo gufunga.
Impamvu isesengura rya diameter nini ya globe valve ikunda kumeneka imbere
Calibre nini yo guhagarika valve isanzwe ikoreshwa mubisohoka, silindiri nkuru, umuyobozi wamazi nindi myanya, iyi myanya ifite ibibazo bikurikira:
1. Byongeye kandi, gutwika ibyuka ntibishobora kuba 100%, bizatera ibyuka byamazi amazi meza ni manini, byoroshye kubyara cavitation na cavitation kwangirika hejuru ya valve.
2) Ku isohoka rya boiler hamwe na valve yaciwe hafi ya silinderi, kubera ko amavuta ava muri boiler, habaho ubushyuhe bukabije rimwe na rimwe, mugihe cyo kwiyuzuzamo, niba amazi yo kubitsa yoroshye atari meza cyane, akenshi igwa igice cya acide nibintu bya alkali, hejuru yikimenyetso bizatera ruswa nisuri; Ibintu bimwe na bimwe bishobora gutondekwa birashobora kandi kuba bifatanye na valve ifunga hejuru ya kristu, bigatuma valve idashobora gufungwa neza.
3) Kwinjira no gusohoka kwa valve ya sub-silinderi, kubera ko gukoresha amavuta nyuma ya valve biterwa nibisabwa kubyara umusaruro nizindi mpamvu, gukoresha amavuta ni binini kandi bito, mugihe habaye impinduka nini mubipimo bitemba, ni byoroshye kubyara flash, cavitation nibindi bintu, bityo bigatera isuri, cavitation nibindi byangiza hejuru yikimenyetso cya valve.
4) Mubisanzwe, iyo hafunguwe imiyoboro minini ya diameter ya pipe, birakenewe ko dushyushya umuyoboro, kandi inzira yo gushyushya ubusanzwe isaba urujya n'uruza rw'amazi kugira ngo inyure, kugirango umuyoboro uhindurwe buhoro kandi bingana kurwego runaka mbere ya valve yaciwe irashobora gufungurwa byuzuye, kugirango wirinde kwaguka gukabije guterwa no gushyushya byihuse umuyoboro no kwangiza igice cyihuza. Ariko muriki gikorwa, gufungura valve akenshi usanga ari bito cyane, bigatuma igipimo cyisuri kiruta kure cyane ingaruka zisanzwe zikoreshwa, bigabanya cyane ubuzima bwumurimo wububiko bwa kashe.
Diameter nini ihagarika valve ihindura igisubizo kitoroshye
1) Mbere ya byose, birasabwa guhitamo inzogera zifunga isi yose kugirango wirinde ingaruka ziterwa no guhangana na plunger valve na packing valve hanyuma uhindure byoroshye.
2) intebe ya spol igomba kuba ikozwe mubikoresho bifite isuri nziza kandi ikora neza, nka karbide ya Siteli;
3) Birasabwa gukoresha imiterere ya disiki ebyiri, bitatewe no gufungura duto guterwa nisuri ikabije, bigira ingaruka kumurimo wa serivisi n'ingaruka zo gufunga.
